The invention discloses a telescopic rod manufacturing method. The telescopic rod manufacturing method comprises the following steps of preparing a plurality of first arc-shaped pieces and a plurality of second arc-shaped pieces, preparing a first ball shaft and a second ball shaft, assembling the plurality of first arc-shaped pieces into an outer cylinder, assembling the plurality of second arc-shaped pieces into an inner cylinder, arranging the inner cylinder in the outer cylinder in a sliding manner, arranging the first ball shaft at one end of the outer cylinder, and arranging the second ball shaft at one end, far away from the first ball shaft, of the inner cylinder. The outer cylinder, the inner cylinder and the ball shaft of a telescopic rod are all independently manufactured, the outer cylinder and the inner cylinder are formed by assembling the multiple first arc-shaped pieces and the multiple second arc-shaped pieces respectively, a cylindrical structure is split into the arc-shaped structure, and t
